Abstract

Although mechanisms of acquired resistance of epidermal growth factor receptor (EGFR)-mutant non-small-cell lung cancers to EGFR inhibitors have been identified, little is known about how resistant clones evolve during drug therapy. Here we observe that acquired resistance caused by the EGFR(T790M) gatekeeper mutation can occur either by selection of pre-existing EGFR(T790M)-positive clones or via genetic evolution of initially EGFR(T790M)-negative drug-tolerant cells. The path to resistance impacts the biology of the resistant clone, as those that evolved from drug-tolerant cells had a diminished apoptotic response to third-generation EGFR inhibitors that target EGFR(T790M); treatment with navitoclax, an inhibitor of the anti-apoptotic factors BCL-xL and BCL-2 restored sensitivity. We corroborated these findings using cultures derived directly from EGFR inhibitor-resistant patient tumors. These findings provide evidence that clinically relevant drug-resistant cancer cells can both pre-exist and evolve from drug-tolerant cells, and they point to therapeutic opportunities to prevent or overcome resistance in the clinic.

  • Several groups have reported that resistance clones are not preexisting but occur via epigenetic adaptation of drug-tolerant persisters whereby some undergo further evolution to acquire genetic resistance mechanisms.

    “Several groups have reported that resistance clones are not preexisting but occur via epigenetic adaptation of drug-tolerant persisters whereby some undergo further evolution to acquire genetic resistance mechanisms (45–47).”
  • A characteristic feature of drug-tolerant cells is evasion of drug-induced apoptosis.

    “A characteristic feature of drug-tolerant cells is evasion of drug-induced apoptosis [25].”
  • In the authors' study, 5-10% of PC9 pools developed rapid resistance due to acquisition of the EGFRT790M resistance mutation as early as 2 weeks after initiating gefitinib treatment.

    “This resulted in two treatment outcomes: a minority of pools (5–10%) developed rapid resistance due to acquisition of the EGFRT790M resistance mutation as early as 2 weeks after initiating drug treatment (early-resistant clones)”
  • Lineage tracing with DNA barcoding confirmed that early-resistant clones were derived from rare pre-existing EGFRT790M-positive cells in the parental PC9 cell line.

    “Lineage tracing with DNA barcoding confirmed that the early-resistant clones were derived from rare pre-existing EGFRT790M-positive cells that existed in the parental PC9 cell line.”
  • The drug-tolerant persister state can serve as a cellular reservoir from which clones that evolve bona fide drug-resistance mechanisms can emerge.

    “These tumor subpopulations can evade strong selective drug pressure by entering this drug-tolerant “persister” state which can then serve as a cellular reservoir from which clones that evolve bona fide drug-resistance mechanisms can emerge [25,26].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
